Page 158 of the 9/11 Commission Report:
While in Karachi, ["9/11 principal architect" Khalid Sheikh Mohammed (KSM)] also discussed how to case flights in Southeast Asia. KSM told them to watch the [cockpit] doors at takeoff and landing, to observe whether the [pilots] went to the lavatory during the flight, and to note whether the flight attendants brought food into the cockpit.
Page 245 of the 9/11 Commission Report:
["9/11 key facilitator" Ramzi Binalshibh and American Airlines Flight 11 ring-leader / hijacker Mohamed Atta believed the] best time to storm the cockpit would be about 10-15 minutes after takeoff, when the cockpit doors typically were opened for the first time. Atta did not believe they would need any other weapons. He had no firm contingency plan in case the cockpit door was locked. While he mentioned general ideas such as using a hostage or claiming to have a bomb, he was confident the cockpit doors would be opened and did not consider breaking them down a viable idea.

The "hardened cockpit doors" are routinely opened throughout the flight--with only flight attendants and drink-carts or flight attendants alone in front of them--therefore, they are not a "correction. The 2017 U.S. Department of Transportation / Office of Inspector General Audit Report concluded those 2 methods were "ineffective":
As an example, the [Radio Technical Commission on Aeronautics DO-329 study] report concluded that some improvised secondary barriers, such as a flight attendant with a galley cart, were ineffective "as tested," and additional enhancements were required to raise the effectiveness of certain barrier methods to an acceptable level.

JetBlue Airways has A320s and A321s have cockpit doors that open away from the cabin, and there are no drink-carts. A319s, B767s, and B777s also have cockpit doors that open away from the cabin. All of these aircraft seat more than 75 passengers.

Most experts know that 1-inch box-cutters did not cause 9/11, that's why TSA allows scissors with blades under 4 inches in carry-ons. Scissors can do more damage than 1-inch box-cutters:

The box-cutters were to kill the pilots and prevent them from going to the back of the jets to give 33 to 81 passengers the hope to over-power only 2-3 muscle hijackers using fake bombs, box-cutters, and pepper-spray to protect the 2 hijacker-pilots.

Not sure what the OIG's reports on poor use of budget dollars have to do with this but I would suggest if cockpit barriers are mandated then there is no use to have an $8,000,000.00 expenditure for FAM's going forward.
No one knows what happened to these perfectly good aircraft in good weather: TWA Flight 800, Air France Flight 447, Helios Airways Flight 522, Egyptair Flights 990 and 804, and Malaysia Airlines Flight 370 . Only conflicting reports by the different agencies who investigated. Technology still cannot definitively tell us what happened. A cockpit rush attack could have prevented pilots to make any emergency transmissions.
